摘要： A control coupling for torque transmission between a pair of rotary members coaxially arranged for relative rotation, which includes a cylindrical casing mounted on one of the rotary members for rotation therewith, a friction clutch assembled within the casing, a piston axially slidably coupled within the casing for rotation therewith and being in engagement with the friction clutch, an end wall member coupled with the casing for rotation therewith and spaced from the piston to form a fluid chamber filled with an amount of viscous fluid, and a rotor disposed in the fluid chamber and mounted on the other rotary member for rotation therewith. The rotor has a plurality of radial blades extending radially outwardly therefrom and being disposed between the piston and the end wall member. The radial plates each have a base portion thickened in an axial direction to increase the amount of viscous fluid stored in the fluid chamber and an outer end portion formed thinner than the base portion, and each internal surface of the piston and end wall member exposed to the fluid chamber is formed to correspond with the opposite surfaces of the radial blade.

摘要： According to the present invention, even if a plurality of operators perform gesture operations in three-dimensional space, the three-dimensional spatial gesture of each operator is accurately associated with the target object of the three-dimensional spatial gesture. For this, a projector displays at least one selection-target object on an upper surface of a table. When a pointer operated by an operator comes in contact with the upper surface of the table, a two-dimensional coordinate detecting apparatus detects the contact position, and determines which object has been designated by the operator. In this stage, among pointers detected by a three-dimensional coordinate detecting apparatus, a pointer having a position closest to the contact position is determined, and the pointer determined to be the closest is decided as a tracking target. Thereafter, the tracking-target pointer is tracked by the three-dimensional coordinate detecting apparatus to determine the operator's gesture pattern.

摘要： A recess (16a3) is provided to be continuous with the circumferential edge of a tray recess (16a2) of a disk tray (16) housing an optical disc (28) to allow a pickup (45) to move without contacting anything. A cover section (17c) having a substantially tongue-like shape adapted to the recess (16a3) is projected integrally from a rotor support member (17) covering the tray recess (16a2) from above and defining a substantially cylindrical housing space (18) for coaxially housing the optical disc (28), the cover section continuously covering the recess (16a3) of the disk tray (16) and the housing space (18). Even when the optical disc (28) is rotated at a high speed, flutter attributable to airflow or a difference between pressures on both sides of the optical disc (28) can be reduced to allow the optical disc (28) to rotate with stability.

摘要： A vibration-transmitting tablet and coordinate-input apparatus at low prices, which enable to easily manage precision of vibration detection position. A vibration-input pen inputs vibration, generated by its vibrator, onto the vibration-transmitting tablet formed by polarizing a piezoelectric member in its thickness direction. When the vibration propagated on the vibration-transmitting tablet reaches four electrodes provided at predetermined positions of the vibration-transmitting tablet, electric signals based on the vibration are detected from the respective electrodes. A signal-waveform detector detects arrival of the vibration at the electrodes based on the electric signals. An arithmetic controller calculates coordinates of the vibration-input position based on arrival timings of the vibration. The arrangement of the electrodes on the vibration-transmitting tablet can be realized by etching, printing or the like, thus management of precision of vibration-detection positions can be much easier.

摘要： A coordinate input apparatus which can stably input coordinates at a high precision is provided. A vibration sensor is fixed to a vibration propagating plate by means such as an adhesion or the like. Electrodes are formed on both edge surfaces of the vibration sensor. One electrode is connected to the vibration propagating plate (its surface is made of a conductive material). Another electrode is connected to a conductive plate spring through an electrode leading member. The electrode leading member has a cylindrical portion to position a projecting portion to a center axis by setting a side surface of the vibration sensor to a reference has a relation adapted to be come into engagement with the vibration sensor. The plate spring presses the electrode leading member to the vibration sensor and is electrically connected to the vibration sensor. Since the position to extract a signal from the vibration sensor is positioned by setting the side surface of the vibration sensor to a reference, the signal can be stably extracted at a high precision.

摘要： When coordinate information is inputted into input device 14, display controller 13 sets input area 16 based on the input coordinate information, and instructs work station (WS) 12 to lower the contrast of the input area 16. The WS 12 then sends an image signal where the contrast of the input area 16 is lowered on the display device 11. This solves the problem that, in a case where the contrast or brightness of a display screen of an electronic board is set for viewers but not for a presenter who inputs characters and figures on the electronic board, the presenter has an uncomfortable feeling from too high contrast or brightness.

摘要： There is provided a highly precise coordinate input device not requiring a particular designating tool. A sheet, composed of a piezoelectric plate polarized in the direction of thickness, is superposed with a vibration transmitting plate, provided with vibration sensors in predetermined positions. The sheet generates vibration by a pulse signal generated by a sheet driver. When the sheet is pressed for example with a pen, the vibration is transmitted to the vibration transmitting plate from the pressed position, and is detected by the vibration sensors. A controller calculates the distance between the vibration input point and the vibration sensor, based on the delay time from the start of vibration to the detection. This operation is conducted for the plural sensors, and the coordinate is calculated from thus calculated distances.
